Surface Mount Schottky Barrier Diodes
Features:
*Extremely Fast Switching Speed
*Low Forward Voltage
*Very Small Conduction Losses
*Schottky Barrier Diodes Encapsulated in a SOT-323 Package
Description:
These schottky barrier diodes are designed for high speed
switching applications circuit protection, and voltage clamping,
Extremely low forward voltage reduces conduction loss,
Miniature surface mount package is excellent for hand held and
portable applications where space is limited.
